Using IBM MQ classes for JMS in IMS

IBM® MQ 8.0.0, Fix Pack 4 adds support for using the IBM MQ classes for JMS in IMS versions 13 and later. You must apply APAR PI45236 to the queue manager for this function to work.

Check the system requirements for the IMS system that your enterprise uses. See Hardware and software requirements for IMS for further information.

This set of topics describe how to set up the IBM MQ classes for JMS in an IMS environment, and the API restrictions that apply when using the classic (JMS 1.1) and simplified (JMS 2.0) interfaces. See JMS API restrictions for a list of the API-specific information.

Note: Similar restrictions apply to the legacy (JMS 1.0.2) domain-specific interfaces, but they are not specifically described here.

Supported IMS dependent regions

The following dependent region types are supported:

MPR
BMP
IFP
JMP (31 bit Java virtual machines (JVMs) only, 64 bit JVMs are not supported)
JBP (31 bit JVMs only, 64 bit JVMs are not supported)

Unless specifically mentioned in the following topics, IBM MQ classes for JMS behaves the same in all region types.

Supported Java Virtual Machines

IBM MQ classes for JMS requires Java SE 7.0 or later.

Other restrictions

The following restrictions apply when using IBM MQ classes for JMS in an IMS environment:
